Human exploration of the future Texas began during the Pleistocene, when lower sea levels exposed a land bridge between Siberia and Alaska and Homo sapiens sapiens migrated into what is now North America. The first explorers and perhaps colonizers possibly reached the continent during a convenient interglacial period, perhaps some 24,000 or more years ago. Other theories of Pre-Columbian exploration suggest that mariners from China, Africa, and the Mediterranean may have reached the New World by following favorable ocean currents. Numerous legends support the idea of transoceanic contacts, but the material evidence remains inconclusive. The first known explorers of Texas were the Clovis people of the Paleo-Indian Stage. An unmistakable presence of bone and stone evidence points to human exploratory and colonizing activity in Texas after 11,500 B.P. Clovis stone projectile points have been found in playas and ancient springs in the far north (Blackwater Draw, the Lake Theo Site, qqv Lubbock Lake, and Miami), and in rockshelters and stratigraphic layers in South and Central Texas (Aquarena Springs and the Levi Site qqv
